Hi Guys,
i've inherited a CephFS-Cluster, I'm fairly new to CephFS.
The Cluster was down and I managed somehow to bring it up again.
But now there are some Problems that I can't fix that easily.
This is what 'ceph -s' is giving me as Info:

Could someone please put me in the right Direction about what to do to fix the Problems?
It seems that two OSD are full, but how can I solve that, if I don't have additionally hardware available?
Also it seems that the Cluster has different ceph-versions running (Hammer and Jewel), how to solve that?
Ceph-(mds/-mon/-osd) is running on Scientific Linux.
If more Info is needed, just let me know.
Thanks in Advance,
Steininger Herbert
